Application filed May 3, 1917. Y Serial No. 166,182.

To all LU/tom t may concern L Be it known that I, PERLEY A. CQ'MBS, acitizen of the United States, residing in the city of Portland, countyof Multnomah, and State of Oregon, have invented certain new and usefulImprovements in Clutches, of which the,` following 1s a spec1cat1on- Myinventionrelates to clutches, and more particularly to an improvedmeans; for operatmg a clutch member, Aand 1t has among its salient'objects to provide a clutch construction in which the movable clutchmember can be moved out` of engagement with a driven clutch element onthe'shaft` without` any end thrust on said shaft, thus providing whatmightV Vbe termedV a floating, clutchoperating mechanism. y t e Anotherobject of my invention is to provide a simple and prac-tical leveragenism for operating said clutch.

In order to more clearly explain my improved clutchI have illustratedthe preferred form thereof on the accompanying sheet of drawings, whichI will now describe. Figure 1 is a horizontal-sectionalview of a clutchembodying my invention; i

Fig. 2 is an end view showing the clutchoperating mechanism;` and Fig. 3is a fragmentary end view, looking,

at the left hand side of F ig. 2.

Referring now more in detail to the drawings, 1 designates the drivingshaft to which is keyed a wheel 2, having a concentrically arrangedclutch element 3, made as a part thereof and driven therewith. Slidablymounted on said shaft 1, is a movable clutch element 4, formed as a partof a bearing sleeve 5, provided with a driving element 6, here shown asa sprocket and having at its o oposite end a bearing flange, orshoulder, 17, against which bears a coiled spring 8, the opposite end ofwhich spring bears against a bearing collar 9, also loosely mounted onsaid shaft. A washer 10, is mounted on said shaft and bears against saidcollar 9 at one side, and at its other side it bears against the flange11 of a nut 12, threaded on to the reduced end 13, of the shaft 1. Saidspring 8 operates to normally hold' the movable clutch 4 in drivingengagement with the driven clutch element 3, said spring bearingoutwardly at one end against the collar 9, and inwardly at its other endagainst the flange 7.

I will now describe the means for moving mecha- Specification of LettersPatent. Patented A131'. 15, 1919.

driving the driven clutch; elethe movable clutch element 4 out ofengagement with ment 3.

Two lever members 14 and 15 are pivotally connected to each other, as at16, and provided at their corresponding ends with yoke-like bearingportions 14a and 15a, which bear, respectively, against the outside ofthe washer 10 4and theinner side of the bearing flange or-shoulder 7 ofthe movable clutch member. The opposite end of the lever 15, ispivotally and loosely connected, as at 17, to a base plate 18, one endof which may be turned up, as at .18, to form a rest or support for thelevers 14 and 15, as shown. The pivotal connection of lever 15 to thepin 17 is suiiiciently looseV to permit the movement of said leverslightly laterally in either direction on the support 18, the holethrough said lever being slightly larger f15 are separated, whiletheiropposite-ends areemoved toward each other, which operation alsomoves the bearing collar 9, and the clutch bearing flange, or shoulder,7, toward each other, compressing the spring 8, and thus moving themovable clutch element 4, out of driving engagement with the drivenclutch element 3, without any end thrust on the shaft 1. I prefer toprovide the levers 14 and 15, on their inner faces with cam portions, as14b and 15b, between which the cam portion 2O of the lever 19 moves forspreading said levers 14 and 15.

I am aware that changes in details can be made in my invention withoutdeparting from the spirit thereof, and I do not, therefore, limit theinvention to the embodiment thereof here shown for purposes ofillustration, except as I may be limited by the hereto appended claims.
